  • Effects of Endovascular Radiation on the Proliferation and Apoptosis of Vascular Medial Smooth Muscle Cells in Rabbits after Carotid Endarterectomy

    ObjectiveTo observe the effects of endovascular radiation (ER) on the proliferation and apoptosis of medial smooth muscle cells (SMC) and to discuss the possible mechanisms of radiation in the prevention of vascular restenosis (RS) in rabbits after carotid endarterectomy (CEA).MethodsForty rabbits undergoing CEA were randomly divided into four groups (each group=10) and given a radiation dose of 0, 10, 20 and 40 Gy 32P respectively. Rabbits were killed on the 3rd, 7th, 14th, 28th and 56th day after operation. The specimens were collected and histopathologic examinations were done.ResultsProliferation apparently occurred in the intima and media of carotid the lumen became narrow in the control group on the 14 th, 28 th and 56 th day after operation. While in the radiation groups, proliferation was apparently suppressed and the lumen was much less narrowed (P<0.05). The apoptosis rate of SMCs and PCNA positive cells increased on the 3rd day after operation and reached the peak on the 7th day. There was statistical difference between the ER groups and control group (P<0.01). The effects were much more evident in 20 Gy and 40 Gy groups compared with 10 Gy group (P<0.01).ConclusionER may prevent RS by suppressing SMC proliferation and migration as well as inducing SMC apoptosis. The effects are positively correlated with radiation doses. SMC proliferation and apoptosis occur in the early period after balloon injury, while hyperplasia of intima and medial happens later.

  • Treatment of Coronary Heart Diseases and Carotid Arteriostenosis Through Offpump Coronary Artery Bypass Grafting Combined with Carotid Endarterectomy

    Objective To investigate the effect of combined carotid endarterectomy (CEA) and offpump coronary artery bypass grafting (OPCAB) on patients with carotid arteriostenosis and coronary heart diseases. Methods A total of 121 consecutive patients with carotid arteriostenosis and coronary artery diseases underwent CEA and OPCAB between January 2003 and December 2009 in Nanjing First Hospital of Nanjing Medical University. There were 81 males and 40 females, with their ages ranged from 62 to 72 years (67.2±4.5 years). All patients had 3vessel coronary artery lesions, and there were 3 cases of left main coronary artery lesion. Unilateral carotid arteriostenosis (≥50%) occurred in 95 patients, and bilateral (≥50%) in 26 patients. The occurrence of stroke, myocardial infarction, angina pectoris and other complications after operation was observed, and followup was carried out. Results All patients underwent unilateral CEA including 50 on the right side and 71 left. The mean block time of carotid artery in CEA was 20.5±7.0 minutes. The average number of distal grafts per patient in OPCAB was 2.9±0.3. None of the patients had stroke or myocardial infarction and no perioperative death occurred. Eightyseven patients felt well in terms of their neuropsycho symptoms; 32 felt no change; and 2 worsened. Follow-up was done for all the patients with a follow-up rate of 100%. The mean time of the follow-up was 67.5±12.5 months. During this period, none of the patients manifested stroke, myocardial infarction or neuropsycho symptoms. Conclusion Concomitant OPCAB and CEA is a safe and effective procedure in patients with carotid arteriostenosis and coronary artery diseases. It can reduce the rate of postoperative stroke significantly. However, longterm outcome of the procedure needs operative experience accumulation, longterm follow-up and observation, and serious research and illumination.

  • Comparative Study of Surgical Treatments between Proximal and Distal Types of Chronic Thromboembolic Pulmonary Hypertension

    Abstract: Objective To retrospectively compare the difference of the effects of pulmonary thromboendarterectomy (PTE) between distal and proximal types of chronic thromboembolic pulmonary hypertension (CTEPH). Methods The data of 70 patients (including 44 male patients and 26 female patients, the average age was 46.2 years old, ranging from 17 to 72) with CTEPH having undergone PTE from March 2002 to March 2009 in Anzhen Hospital were retrospectively reviewed. We classified them into two different groups which were the proximal CTEPH group (n=51) and the distal CTEPH group (n=19) according to the pathological classification of the CTEPH. Clinical data, hemodynamics blood gas analysis and so on of both groups were compared. Results There was no perioperative deaths in both groups. Compared with the proximal group, cardiopulmonary bypass time [CM(159mm](189.5±41.5 min vs.155.5±39.5 min,P=0.003), aorta cross clamp time (91.3±27.8 min vs.67.2±27.8 min,P=0.002) and DHCA time (41.7±14.6 min vs.25.7±11.6 min,P=0.000) were significantly longer in the distal group. The incidence of residual pulmonary hypertension in the distal group was significantly higher than that in the proximal group (42.1% vs.13.7%,P=0.013), while the incidence of pulmonary reperfusion injury postoperatively in the proximal group was significantly higher than that in the distal group (41.2% vs.10.5%, P=0.021). SwanGanz catheterization and blood gas index were obviously improved in both groups. However, the pulmonary artery systolic pressure (PASP, 67.8±21.3 mm Hg vs.45.5±17.4 mm Hg,P=0.000) and the pulmonary vascular resistance [PVR, 52.8±32.1 kPa/(L·s) vs.37.9±20.7 kPa/(L·s),P=0.024]  in the distal group were significantly higher than those in the proximal group and the partial pressure of oxygen in arterial blood of the distal group was significantly lower than that of the proximal group (76.7±8.7 mm Hg vs.88.8±9.3 mm Hg,P=0.000). After operation, 70 patients were followed up with no deaths during the followup period. The time of the followup ranged from 2 to 81 months (32.7±19.6 months) with a cumulative followup of 191.8 patientyears. Three months after operation, 47 patients were examined by pulmonary artery computer tomography angiogram (PACTA) and isotope perfusion/ventilation scan, which showed that the residual occlusive pulmonary artery segment in the proximal group was significantly fewer than that in the distal group (isotope perfusion/ventilation scan: 2.2±11 segments vs. 4.7±2.1 segments, P=0.000; PACTA: 3.5±1.4 segments vs. 4.9±2.0 segments,P=0.009). The New York Heart Association (NYHA) functional class and 6 minute walk distance (6MWD) in the proximal group were significantly better than those in the distal group (1.7±0.5 class vs 2.3±0.4 class; 479.2±51.2 m vs. 438.6±39.5 m, P=0.003). Venous thrombosis in double lower limbs reoccurred in two patients. According to KaplanMeier actuarial curve, the freedom from reembolism at 3 years was 96.7%±2.8%. Bleeding complications occurred in three patients. The linear Bleeding rate related to anticoagulation was 2.47% patientyears. Conclusion Although the early and midlong term survival rate of PTE procedure to treat both proximal and distal types of CTEPH is agreeable, the recovery of the PASP, PVR and 6MWD, and blood gases in patients with proximal type of CTEPH are significantly better than those in patients with distal type of CTEPH. On one hand, anticoagulation can singularly provide enough protection to patients with proximal type of CTEPH, but on the other hand, diuretics and pulmonary hypertension alleviation drug should be added to the treatment regimen for patients with distal type of CTEPH after the procedure of PTE.

  • Surgical Treatment for Patients with Diffused Coronary Artery Disease

    Objective To summarize the early outcomes and clinic al experience of off-pump coronary artery bypass grafting (off-pump CABG) afte r off-pump coronary endarterectomy (CE) for patients with diffused coronary art ery disease. Methods From May 2003 to November 2006,83 patients with diffu sed coronary artery disease underwent CE without cardiopulmonary bypass and off-pump CABG. There were 61 males and 22 females with age ranged from 55 to 80 ye ars (65±7 years). There were 7 patients in Canadian Cardiac Society(CCS) an gina classⅡ,20 patients in class Ⅲ,and 56 patients in class Ⅳ. 36(43.4%) pat ients had history of myocardial infarction. Coronary angiogram revealed th at 5 patients had double vessels disease, and other 78 patients had triple ves s els disease with 16 left main stem disease. The left ventricular ejection fract ion(LVEF) ranged from 25% to 65% (51%±16%). One hundred and ten endarter e ctomies were performed in 83 patients totally which included 67 in left anterior descending artery(LAD),9 in circumflex artery and 34 in right coronary artery . Twenty patients received onlay venous patch after CE in LAD and then grafte d by internal mammary artery (IMA) on the patch. There were 83 left IMA, 2 radia l arteries, others were great saphenous veins, the mean number of grafts was 3.9 ±1.2. Results There was no death in all patients. Intraoper ative graft flowmeter was used to check the flow in the grafts before chest cl osure. One hundred and one (92%) out of 110 grafts after CE showed a satisfactor y grafts flow(22±16ml/min) intraoperatively. Four patients had perioperative myocardial infarctions but none had hemodynamic changes. All patients discharged uneventfully. Seventyfive patients (90.4%) had 8 to 50 months followup with no angi na reoccurrence. Eight patients had coronary angiogram from 3 to 29 months af ter operation with all patent grafts to the CE coronaries. Conclusion Off-pump CABG with coronary endarterectomy is feasible and achieves surgical revascularization in patients with diffuse cor onary artery disease.

  • APPLICATION OF VACUUM SEALING DRAINAGE IN SEVERE SKIN CLOSED INTERNAL DEGLOVING INJURY

    【Abstract】 Objective To investigate the effectiveness of the vacuum sealing drainage (VSD) technique with split middle thickness skin replantation for the treatment of severe skin closed internal degloving injury (CIDI). Methods Between July 2008 and April 2011, 16 patients with severe skin CIDI were treated. There were 11 males and 5 females, aged 17-56 years (mean, 28 years). Injury was caused by traffic accident in all cases. The time between injury and operation was 2-8 hours (mean, 5 hours). Peeling skin parts included the upper limb in 3 cases and the lower limb in 13 cases. The range of skin exfoliation was 5%-12% (mean, 7%) of the body surface area with different degree of skin contamination. After thorough debridement, exfoliative skin was made split middle thickness skin graft for in situ replantation, and then VSD was performed. Results After 7 days of VSD therapy, graft skin survived successfully in 14 cases; partial necrosis of graft skin occurred in 2 cases, and was cured after thorough debridement combined with antibiotics for 7 days. All patients were followed up 6-18 months (mean, 12 months). The appearance of the limb was satisfactory without obvious scar formation, and the blood supply and sensation were normal.The joint function was normal. Conclusion For patients with severe skin CIDI, VSD treatment combined with split middle thickness skin replantation can improve the local blood circulation of the limb, promote replantation skin survival, and shorten healing time of wound. The clinical effectiveness is satisfactory.

  • COMPARISON OF EARLY COMPLICATIONS IN TREATMENT OF CAROTID ARTERY STENOSIS WITH CAROTID ENDARTERECTOMY AND CAROTID STENTING

    Objective To compare the early compl ications of carotid stenting (CAS) and carotid endarterectomy (CEA) in treatment of carotid artery stenosis. Methods Between January 2005 and December 2007, 63 patients with carotid artery stenosis were treated with CEA in 36 cases (CEA group) and with CAS in 27 cases (CAS group). There were 42 males and 21 females with an average age of 67.5 years (range, 52-79 years). The locations were the left side in 28 cases and the rightside in 35 cases. The carotid stenosis was 60%-95% (mean, 79%). The major cl inical symptoms were stroke and transient ischemic attack. The cranial CT showed old cerebral infarction in 24 cases, lacunar infarction in 22 cases, and no obvious abnormal change in 17 cases. The encephalon, heart, and local compl ications were compared between 2 groups within 7 days after operation. Results In CEA group, encephalon compl ications occurred in 3 cases (8.3%), heart compl ications in 2 cases (5.6%), and local compl ications in 5 cases (13.9%); while in CAS group, encephalon compl ications occurred in 8 cases (29.6%), heart compl ications in 1 case (3.7%), and local compl ications in 3 cases (11.1%). The encephalon compl ication ratio of CAS group was significantly higher than that of CEA group (χ2=4.855, P=0.028); and there was no significant difference in other compl ications ratios between 2 groups (P gt; 0.05). Conclusion CEA is the first choice to treat carotid artery stenosis.

    Objective To evaluate the feasibil ity and effectiveness of allograft osteochondral transplantation with arthroscopic assistance for osteochondritis dissecans (OCD) associated with large osteochondral defects. Methods From January 2004 to May 2007, 13 patients with OCD with large osteochondral defects were treated. There were 7 males and 6 females, aged 18-59 years with an average of 35.8 years. The locations were left side in 8 cases and right side in 5 cases. The disease course was 7 days to 20 years with the median duration of 42 months. Four cases had obvious sprained history. The involved locations were lateral portion of the medial femur condyle (MFC) in 5 cases, thochlea area of MFC in 2 cases and lateral femur condyle in 6 cases. The range of motion was (95.0 ± 13.5)° and the Lysholm score was 62.23 ± 7.79. According to International Cartilage Repair Society classification system and the Guhl classification of OCD under arthroscopy, all the patients were type IV. Defect areas were 3-7 cm2 with an average of 4.32 cm2. The depths of defects were 0.8-2.0 cm with an average of 1.55 cm. Allograft osteochondral transplantation combining with adsorbable screw was appl ied for the lesions. The patients were closely instructed to do exercise through following up. Results The wounds all healed by first intention Thirteen cases were followed up for 2.2 years (14 months to 4 years) after operation. Three months after operation, 2 cases had pain after continuous exercise for 1 hour, they were directed in the methods of functional exercise and to strengthen their quadriceps femoris. Medicine was given in 2 patients who had sign of friction feel ing of joint 6 months after operation. The range of motion at the last follow-up was (137.0 ± 9.8)°, showing statistically significant difference when compared with that before operation (P lt; 0.05). The X-rays and EMRI examinations at following-up indicated that bone healed well and articular facet was integrity. The Lysholm score was 92.08 ± 7.64 one year after operation, showing statistically significant difference when compared with that before operation (P lt; 0.05). Conclusion Allograft osteochondral transplantation with arthroscopic assistance is a useful method in treatment of OCD with large osteochondral defects of the knees.
